Osmosis - the diffusion of water (across a membrane) Water will move in the direction where there is a high concentration of solute (and hence a lower concentration of water. A simple rule to remember is: Salt is a solute, when it is concentrated inside or outside the cell, it will draw the water in its direction.
Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute. In biological systems, the solvent is typically water, but osmosis can occur in other liquids, supercritical liquids, and even gases.smosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute.
